1. Why would a chemist, when tasked with preparing a small volume of a dilute solution use a dilution technique (i.e., prepare a dilute solution from a concentrated stock solution) rather than just weighing out the exact amount of solid material and dissolving it in the volumetric flask to make one solution only? 2. Calculate the number of grams of CuCl2.2H20 solid needed to prepare 25.00 mL of 0.0450 M CuCl2.2H2O solution. Show your work in the space below. 3....
